I originally got this from Matt Busigin (I think). Average Hourly Earnings multiplied by Average Weekly Hours (Total Private: Nonfarm) gives a pretty good indication of where GDP is headed, well ahead of the BEA accounts.
Remember this is nominal GDP, so the latest (April 2015) figure of 4.38% would need to be adjusted for inflation. Inflation is somewhere between 0.5% and 1.75% depending on how you measure it. The GDP deflator looks like it will come in below 1.0% which would leave us with real GDP of at least 3.38% p.a.
